Security :: Content Filter For Web / Email And Instant Messaging
Apr 12, 2010
I have been assigned a task to implement a free open source content filter having feature of web, email, instant messaging etc. If any one has the information or worked on this type of product please share it.
Is there a program already set up to do this? Probably similar to WASTE (URL...), though waste's client is currently unsupported on the newest version of ubuntu (make error having to do with char* or something). Preferably windows and linux supported. Another thing that could be of use would be a local ssh chat. For example someone connects to my box either as me or as another user and runs 'hiben' and a window (or i ran a command or something and have a window open for it) pops up that we can chat in. Something other than single line messages.
I want a mail server that can work just like MDaemon. The reason is, I want to have an email content filter rule that does some thing like this.
1. If the To Header contains "support@thisdomain" then run a program. What this means is that, there is a program here in the office, and if some one sends an email to the support address, with an attachment of .exe and that person is a customer, then the program should be run. The only thing I need here is if there is a rule or script that can filter email header and run a program.
2. If the Exit Code from a previous 'Run program' rule is in the range of 1 to 100 and if the To Header contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...> and delete this message.
3. If the EXIT CODE from a previous 'Run program' rule is =0 and if the TO HEADER contains "support@thisdomain" then send note1 "to<email address>" from <$SENDER$" "SUBJECT <AM ...> and delete this message.
We have approximately 100 retail locations that will have split vpn tunneling. Intranet traffic will flow over the vpn to the corporate headquarters, voip traffic will tunnel to a regional hub and internet bound traffic will go over the local isp. The retail locations are small with 1-8 users and no enterprise grade equipment (servers, etc). This setup in effect will render our current content filtering solution useless.
The locations will be equipped with Cisco ASA 5505 Firewalls. The original plan was to use a Websense server and the url filtering feature to act as a content filter. I just found out that pricing for Websense was not included in the budget will be a show stopper.There may also be some performance issues with this method. Putting a proxy server at each location is not really an option. We do not have the resources to place a server at each location, plus the users could simply unplug an inline device or go around it. There is minimal supervision at most of these locations.
Ideally, I would like to find a way to use something like Dansguardian with an ldap interface and the url filtering feature of the ASA firewalls. I found a program called n2h2p, but I can find 0 documentation for it. It is also 2 years old with no updates. I also need to be able totrally manage this as trying to keep up with 100 different configurations for 400 users would be virtually impossible for the amount of time I will have available
I'm a Linux newbie and for my new job I have to do a lot of instant messaging to clients. They are on a variety of services, aim, icq, msn, myspace, facebook, yahoo, Google Talk, jabber, and .mac/ichat Is there a good instant messaging client that covers most of these on one application? I am using Mandriva with KDE 4.2.
I booted up my laptop as usual and found that when I opened Empathy IM Client it would not allow me to login when I changed the status to Online (or equivalent). Normally as soon as I open the client the Messaging Status can be changed in the top right next to the clock so I tried to remove it but unfortunately it took the shut down panel with it.
To try and bring them back I used the restore panel commands in terminal:
Using CentOS. I have a cron setup to run this command: Code: /var/test.sh | mail -s "Test Cron" firstname.lastname@example.org The email is sent but the output of the script is not in the email body, it's just blank. I know there is some output because there are some echo statements in the script.I don't want to get an email for all cronjobs, just this one.
I want to write a program to filter web content. I believe that i can write a filter program by usig java however problem is that how can i place this program like "internet -> filter -> web browser" ?
I have the following command that I run on cygwin:
find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | xargs du --max-depth=0 > foldersizesreport.csv
I intended to do the following with this command: for each folder under /d/tmp/ that was modified in last 150 days, check its total size including files within it and report it to file foldersizesreport.csv however that is now not good enough for me, as it turns out inside each
so as you see inside each subfolderX there is a file named somefile.properties inside it there is a property SOMEPROPKEY=3808612800100 (among other properties) this is the time in millisecond, i need to change the command so that instead of -mtime -150 it will include in the whole calculation only subfolderX that has a file inside them somefile.properties where the SOMEPROPKEY=3808612800100 is the time in millisecond in future, if the value SOMEPROPKEY=23948948 is in past then dont at all include the folderin the foldersizesreport.csv because its not relevant to me.so the result report should be looking like:
and if subfolder3 had a SOMEPROPKEY=34243234 (time in ms in past) then it would not be in that csv file.so basically I'm looking for:
find /cygdrive/d/tmp/* -maxdepth 0 -mtime -150 -type d | <only subfolders that have in them property in file SOMEPROPKEY=28374874827 - time in ms in future and not in past | xargs du --max-depth=0 > foldersizesreport.csv
last friday my schools isp enabled iwsva - interscan web security virtual appliance from trendmicro. all traffic is now filtered, and slowed down. videos and other videostreams are now useless. after this we have had serious problems using our netbooks with ubuntu, and upgrading workstations with ubuntu has become very problematic, or almost impossible. i have to run the update process 6-8 times before all packages are updated.
what can i do to document the problem in a good way. the isp tells me that there are no problems, and that it has to be a linux problem. (ever heard that one before?) the ltsp-clients on my debian servers does not have the same problems, maybe because they are using the proxy on this server?
I have had a search for this problem, but have not found a match: undoubtedly it is so straightforward that no-one has needed to ask it before: I have two accounts in Evolution, work and gmail. I would like my work email (which I check via IMAP) to be copied locally as it comes in so that I can file it properly, but also kept on the server so that I can access through my laptop.
I have set a message filter which does the following: Code: IF status is not read THEN set status read copy to folder Inbox Stop processing The filter works (if I apply manually then it goes) AND I have set the preferences to apply filters automatically, but no joy when a new email arrives.
Looking for some advice and guidance please? Which free Instant Messaging server & Email server is best for SUSE 11.4?I have an office with a mix of approx 20+ Windows 7, Macs desktops, and we want to bring our email and instant messaging services/solution in house.Im technical, so am not afraid to dive in feet first, but being relatively new to Linux can anyone advise a good free product(s) which would work in this kind of setup bearing in mind the windows and mac desktops need compatible clients?
We have MS Exchange email server with postfix/amavis on FreeBSD as proxy for anti-spam and anti-virus. We use our own developed CRM and trying to implement such functionality that when CRM manager send email to CRM client or vice versa through email client like Outlook (no plugins for CRM) this message would be shown in CRM. There is already a solution to parse emails from specific emailbox and show it in CRM.
What I need is to create postfix email filter to check if sender email is in file CRM_managers_emails and recipient email is in file CRM_clients_emails then forward that email to [URL] Filter should check both incoming and outgoing messages. I will auto generate CRM_managers_emails and CRM_clients_email files containing all such emails taken from CRM database. I know i should use something like Postfix After-Queue Content Filter but most of examples are for blocking emails.
Is there a way you could update content on a web page from an incoming email on a linux server? e.g. you email your comments to an email address and the contents of your email (comments) appear on a web page. (preferably in real time but some delay acceptable)
I am planning an issue tracking system that I will build in Django and Python and host on a Debian server. Being an issue tracking system it will have to send and receive emails. I can easily configure the send mail functionality using python inbuilt functions. But is there a way to create new content from an incoming email?
e.g. scenario > User sends email to email@example.com and the issue management system picks up that email (somehow) and creates a new issue based on contents of the email (preferably in real time but some delay is acceptable).
I have looked at postfix and sendmail but neither allows you create new content (issue) from an incoming email. Any thoughts?
Quote:One of the new features in Firefox 4 that we are very excited about is Content Security Policy, which is a mechanism that works behind the scenes to prevent some of the more severe web-based attacks against users and websites.Firefox users don?t have to do anything in order to gain this protection. Simply install Firefox 4 and you will instantly receive all of the benefits that Content Security Policy has to offer. Easy!
We operate a small ISP and are currently using a debian distro as our gateway server.Recently we have had an increased number of spam issues with customers (not them sending it directly, rather the customer getting infected with a virus/malware and then their computer becoming a bot).I'd like to set up another gateway of sorts to sit after our authentication gateway but before our backbone to provide spam filtering (and hopefully virus filtering) for any traffic passing through which might be email.I've tried searching for any linux based software which would suit, but I'm coming up empty.
Surely there's something already out there which can perform this task.Finally, just to clarify, I'm not talking about spam filtering for email accounts we host ourselves (this is built into our mail server); I'm talking about spam originating from customers PC's which is passing through our gateway (but not our mail server).
What is a good IP filter/firewall program? Seeing as how I like free softwares, I download a lot of torrents. When I was using Windows, I used PeerBlock (the newer fork of PeerGuardian), however, it's not available for Linux. What would be a good alternative for this in Linux? I tried iplist as it has a GUI, and it was extremely buggy and blocked random web pages even after I put them on the exceptions list. And MoBlock has no GUI from I understand, nor has it been updated in years.
I have a batch job which logs in to the server every 10 minutes via windows rsh. The job checks to see is there are any files that need to be send via a EDI serverto a supplier.The following logwatch report is swamped with the login messages and would like to either suppress the logging in PAM? or suppress the entry in the logwatch report?But I still want logging id the username is not username1.Connections (secure-log) Begin rshd: pam_rhosts_auth(rsh:auth): allowed to firstname.lastname@example.org as myedi
I followed this How To (https://help.ubuntu.com/community/Postfix) in order to add smtp authentication to my Postfix installation used as spam filter for my exhange server, and it'seem all ok; the only thing that I don't understand is where I list all the users (with passwords) that I authorize to send mail through my server...
